7024 CE/HCP4ADGA Bearing Product Overview & Core Advantages
The 7024 CE/HCP4ADGA is a precision angular contact ball bearing designed for the most demanding applications. Engineered to a P4A super-precision tolerance, it delivers exceptional rotational accuracy and dimensional stability. A key advantage is its ability to accommodate combined loads (radial and axial) simultaneously, while its universal matchable (SU) design allows for flexible mounting in preloaded sets to achieve optimal stiffness and system performance. The combination of a ceramic ball and phenolic cage makes it an ideal choice for high-speed operation and extended service life.
7024 CE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7024 | Basic bearing series and size designation (120mm bore, 180mm OD). |
| CE | Indicates a 15° contact angle and specific internal design optimized for high-speed performance. |
| HC | Signifies the use of Hybrid Ceramic balls (Silicon Nitride), which reduce friction, heat generation, and wear. |
| P4A | Denotes a super-precision tolerance class, exceeding ABEC 7/ISO P4 standards, for superior running accuracy. |
| DGA | Specifies a phenolic (polyamide) cage and an Extra Light (A) preload for high-speed, low-torque applications. |
7024 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and System Stability: The universal matchable (SU) design allows two bearings to be mounted in a back-to-back or face-to-face arrangement, creating a preloaded set that significantly increases system rigidity and resistance to moment loads.
- Superior High-Speed Capability: The lightweight phenolic cage and low-density ceramic balls minimize centrifugal forces, enabling a high limiting speed of 16,000 rpm. The 15° contact angle is optimized for high-speed axial loads.
- Exceptional Load Capacity: With a high dynamic load rating of 21,060 lbf, this bearing is built to handle significant combined loads over a long operational life.
- Precision and Longevity: The P4A tolerance ensures minimal runout and vibration, which is critical for precision machinery. The hybrid ceramic construction offers superior resistance to wear and a longer service life compared to all-steel bearings.
7024 CE/HCP4ADGA Bearing Typical Application Areas
This high-performance precision angular contact bearing is ideally suited for applications requiring high speed, high rigidity, and exceptional accuracy, such as:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Gearboxes
- High-Frequency Motors and Spindles
- Aerospace and Defense Systems
- Medical and Laboratory Equipment
